HERBERT WILLIAM BAMBER, OF LONDON, ENGLAND, ASSIGNOR TO' MAURICE STEIN-MAN BEZENCENET, 0F LONDON, ENGLAND.

GAS PRODUCER FOR 'USE IN AUTOMOBILES AND THE LIKE.

Application mea November 23, 1921., sei-iai No. 517,244.

To all whom t may concern l Be it known that I, HERBERT WILLIAM BAMBEP.,a subject of the King of Great Britain, and a resident of London,England, have invented certain new and useful Improvements in GasProducers for Use in Au- A tomobiles and the like, of which the folplyfor internal combustion engines as used for automobiles, small marinecraft, port- Valple sets for agricultural purposes, and the li e.

AOwing to the comparatively small size of such producers and thenecessity of keeping down the aggregate weight of the apparatus it isessential that the parts susceptible to wear and tear or o-ver heatingshould be readily replaceable and the object of the present invention isto obtain this desirable end besidesv simplifying the generalconstruction and assemblage of 'the several parts.

For this purpose a producer constructed in accordance with my presentinvention comprises an inner steel chamber preferably of cylindricalform with or without a refractory lining that serves as the producer, orthe inner chamber may be made of a refractory material without theenclosing steel chamber. This steel or inner chamber is provided with anexternal flange situated near its top that rests on a flange provided onthe external shell or casing whereby an annular space or air passage isformed that surrounds the producer. To the base of this external shellor casing is aihxed by any suitable means the ash nit which supports thegrate with the upper surface of which the inner refractory chambercontacts. The ash pit is provided with the usual door for the removal ofashes. The grate is mounted on an axis or spindle situated at theopposite side of the ash-pit from the door and provided with means forlowering the said grate into the ash pit Vin order to lfacilitate theremoval of clinker and ashes from the interior of the furnace. Thespindle is preferably made hollow or tubular and at the outside endthereof may be affixed a float chamber which is supplied with water by aflexible pipe connection with the water storage tank, a suitable pipeconnection being made with said tubular spindle to the small steamgenerator or boiler which is formed as an integral part of the graten Bythis means a constant level of water is maintained in the boiler. Alever is provided by means of which the grate can be raised or loweredas may be required suitable retaining mechanism being employed forkeeping the grate in its normal raised position adjacent to the base ofthe producer, ri`he upper part of the external shell or casing carriesthe usual `feed hopper and the space between the inner chamber and theouter shell, above the flanges by which the two are held together, formsan annular collecting chamber for the gas issuing from the producer andthe outlet conduit is fixed to this part of the shell to convey the gasto the-scrubber or elsewhere as the case mav be.

In order that my invention may be readily understood in the annexeddrawing, there is illustrated a producer with v my improvements appliedthereto in which Figure l is a vertical section, Figure 2 a similarsection as viewed from left to right of Figure l and Figure 3 is avertica-lsection of a modified form of construction similar' letters ofreference in all the figures relating to like parts.

Referring now to Figures l and 2 the producer comprises an inner steelchamber a of cylindrical form with a refractory lining Y) that rests onan internal flange c. The inner chamber a; is provided with an externalflange d that rests on and is bolted to the top flange e of the shell orcasing f in such a manner as to form therewith the annular air space gsurrounding the producer. The base of the external shell or casing j issecured to the ash pit h bv any suitable means as for example as shownby resting in the annular groove i at the top of the ash pit It andsecured therein by bolts or set screws j. The ash pit it is providedwith the usual door lc for the removal of ashes and the grate m contactswith the lower end of the inner chamber a and is swivellably mounted onthe axis or spindle a supported by the bracket 0 in such a manner thatit can be lowered in the ash pit 7L as shown in dotted lines in Figure 2the operation being effected by the manipulation of the lever p whilstthe fore part of the grate is retained in its normal working position bythe strut g pivotally Xed to the front of the grate m.

The spindle n is preferably made hollow or tubular and at the outsideend thereof may be aiiixed a float chamber of any convenient and wellknown type for the maintenance of a constantlevel of water within theboiler or vaporizer r the service thereto being established by the pipe8 and the connection to the float chamber (not shown in drawing) by theflexible pipe t. The boiler shown in the drawing is of the typedescribed in U. S. Patent 1,420,570, but any other form of vaporizer maybe employed. The upper part of the external shell or casing carries theusual feed hopper uf and the space between the inner chamber a and thesuperstructure e, above the flanges l and e by which the parts are heldtogether, forms an annular collecting charnber w for the gas issuingfrom the producer which may be led away therefrom by a conduit not shownfixed to the outlet y leading to the scrubber or elsewhere as the casemay be.

ln the modification illustrated in Figure 3 it will be observed that theinner refractory lining has been dispensed with and it will be obviousthat instead of a metal interior the producer may be of refractorymaterial unsupported by a metallic casing.

It will be understood from the foregoing description that presuming theremoval of the feed hopper u and superstructure f1) the inner chamber atogether with its lining when the latter is employed, can be removedbodily without disl turbing the other parts of the producer. Similarlythe base or` ash pit h together with theV grate m can be entirelyremoved from the producer by the removal of the few bolts y' used tojointhe shell f and ash pit 7L together so that the renewal ofthe variousparts can be effected very expeditiously, if and when required. l

Air is injected at A, into the annular spaceV g between the wall of thechamber a and the shell or casing f, passesV downwardly into ash pitwhence it makes its way upwardly through the grate bars and mixed withsteam passes through the glowing incandescent fuel in the chamber a. Y

What I claim is Y A gas producer comprising an'innergenerating chamberprovided with a 'single external flange at its upper end, van outermetallic casing surrounding said generating chamber and an ash pitdisposed below said chamber, the upper end of said casing having aflange that supports, and is removably secured to, said external flangeand the lower end of said casing resting inan annular groove in the topof the ash pit, a grate swivellably mounted on Va tubular axis with- Intestimony whereof I affix my signature.
